The invention relates to a rotationally symmetrical coupling comprising an annular hub made of a rigid material, which is surrounded by an outer ring made of a rubber-elastic material. The coupling also comprises an outer contouring, which is located on the outer diameter and which is provided for positively transmitting torques, whereby the outer ring is reinforced by an embedded, annular, rigid solid body. The aim of the invention is to achieve a quieter operation of a coupling of the aforementioned type and to better protect this coupling from becoming damaged. To these ends, the invention provides that the rubber-elastic material is silicone and that the annular, rigid solid body, on the outside, has a shape, which is similar to that of the outer contouring of the outer ring and which maintains, over the circumference, a nearly constant distance from the outer contouring of the outer ring. The rigid solid body is preferably comprised of a curved, metallic strip material having a constant thickness.
